Rename efx_rx_scale_support_get() to efx_rx_scale_default_support_get(),
and efx_rx_hash_support_get() to efx_rx_hash_default_support_get().

All these really report is whether an exclusive RSS context was
successfully acquired at efx_rx_init().

efx_rx_scale_support_get() sounds like it reports whether the device
supports RSS, and whether exclusive or shared contexts are supported,
but it doesn't do that. Renaming it to
efx_rx_scale_default_support_get() helps to reflect that it reports
what RSS support the client gets without trying to allocate RSS
contexts itself.

Also rename efx_rx_scale_support_t to efx_rx_scale_context_type_t, to
make the enum more suitable for specifying the type of an RSS context
to be allocated.

Make the existing filter-specific define more general.
This is the same as MC_CMD_RSS_CONTEXT_ALLOC_OUT_RSS_CONTEXT_ID_INVALID.

On Medford, with full-featured firmware running, encapsulated
packets may not be delivered unless filters are inserted for
them, as ordinary filters are not applied to encapsulated
packets. So filters for encapsulated packets need to be
inserted for each class of encapsulated packet. For simplicity,
catch-all filters are always inserted. These may match more
packets than the OS has asked for, but trying to insert more
precise filters increases complexity for little gain.

This supports filters which match all unicast or multicast
inner frames in VXLAN, GENEVE, or NVGRE packets.
(Additional fields to match on can be added easily.)

Tx/Rx queue may be already flushed due to Tx/Rx error on the queue or
MC reboot. Caller needs to know that the queue is already flushed to
avoid waiting for flush done event.

MCDI results returned in req.emr_rc have already been translated
from MC_CMD_ERR_* to errno names, so using an MC_CMD_ERR_* value
is incorrect.

Improve error checking to avoid a caller overflowing the MCDI
request buffer if the requested TXQ size was excessively large.
